Difference betwen org.wildfly.bom and org.jboss.spec for Java EE7 with maven -

i working in new project going use java ee 7 wildfly, still confused maven dependencies should use. have found these 2 groups apparently can use: org.wildfly.bom , org.jboss.spec

they have following predefined artifact use in projects (searched in https://repository.jboss.org/nexus/index.html#welcome):

org.wildfly.bom:

• jboss-javaee-7.0-with-all
• jboss-javaee-7.0-with-hibernate
• jboss-javaee-7.0-with-tools
• jboss-bom-parent
• jboss-javaee-7.0-with-transactions
• jboss-javaee-7.0-with-security
• jboss-javaee-7.0-with-resteasy
• jboss-javaee-7.0-with-infinispan
• jboss-javaee-7.0-with-hibernate3

org.jboss.spec:

• jboss-javaee-all-7.0
• jboss-javaee-web-7.0
• jboss-javaee-7.0

also have realized that can see dependency hierarchy using org.jboss.spec not wildfly.bom. so, question difference?, 1 suggest?

the org.wildfly.bom includes dependencies versions of hibernate, resteasy, etc. dependencies used in wildfly. if use jackson2 annotations org.wildfly.bom:jboss-javaee-7.0-with-resteasy should include correct version of jackson2 dependency.

the org.jboss.spec include java ee 7 api's used.

if you're not using specific wildfly use org.jboss.spec bom. if you're using specific server includes, jackson2, infinispan, etc., i'd use org.wildfly.bom.
